Apocalypse Architect: A Tower Defense LitRPG

Chapter 73: Return to Outpost 15

Jax didn’t waste time on pleasantries. He cut straight to the tactical assessment.

“The Spiked Dune Lord,” Jax pressed, his eyes narrowing. “Did you get intel on it? How is Redrock Bastion reacting?”

Silas nodded grimly, wiping rain from his face. “That’s the main issue. The entire leadership at Redrock Bastion is tracking it. They aren’t just watching; they’re actively helping The Sprawl build fortifications. Defense Tower deployment has accelerated across the entire city. They’re terrified.”

The room went silent. If the major powers were scrambling, the threat was cataclysmic.

“Do we have specifics on the target?” Jax asked.

“Yeah. It’s bad,” Silas said, leaning forward. “It’s an evolving bioweapon. A few years back, Redrock researchers classified the Spiked Dune Lord as a Tier 1 threat. Manageable. But in less than two years, it’s mutated. The one heading our way? It’s confirmed as a Tier 4 entity.”

“What?”

The word hung in the air like a guillotine blade. Kaleb’s jaw dropped.

“A Tier 4 Insectoid?” Gareth stammered, his face draining of color. “You’re joking. That Tier 3 Arachnid nearly wiped us out! How the hell are we supposed to fight a Tier 4?”

“He’s right,” another survivor whispered, gripping his weapon until his knuckles turned white. “Tier 4s are myths. Are we even capable of scratching it?”

“Damn it,” Silas muttered, running a hand through his damp hair. “I knew the pressure out there felt wrong. Tier 4… that explains why the atmosphere feels like a graveyard.”

Jax felt a cold knot tighten in his stomach. The battle with the Acid-Web Arachnid had been a desperate scramble for survival. Facing a creature exponentially stronger wasn’t a fight; it was an execution.

“Anything else?” Jax asked, keeping his voice steady to prevent panic from spreading.

“The experts released an ecological report,” Silas continued. “The Spiked Dune Lords are apex predators. Their primary food source? Rodent-Maw Creepers. That’s why the Creepers have been scarce in other sectors—they’re being hunted. Most Outposts only see a few dozen stragglers. Nobody sees hundreds at a time… except us.”

Jax cursed silently.

It was his System missions. The System was spawning localized waves of Creepers to test him, but in doing so, it had turned his fortress into an all-you-can-eat buffet for the Spiked Dune Lord. He wasn’t just defending a base; he was guarding a dinner plate.

“And those Hive Spires we saw?” Silas added. “They’re incubators. The Dune Lords lay eggs inside. Once they hatch, the larvae gorge on the Creepers to accelerate their growth.”

Jax pieced the horror together. The Creepers guarded the Spires not out of loyalty, but because they were livestock waiting for the slaughter.

“If the larvae reach adulthood,” Silas said quietly, “the experts predict they could surpass Tier 5.”

The silence in the room deepened.

A Tier 5 Insectoid would reduce The Sprawl to rubble. Even with hundreds of Defense Towers, the city wouldn’t stand a chance. The mucus shielding on a beast that size would shrug off standard ballistics like rain.

Jax walked to the viewport, staring at the concrete walls of his fortress. They looked sturdy, but against a Tier 4 subterranean leviathan? They were paper.

“If it really is a Tier 4,” Jax said, a humorless smile touching his lips, “these walls won’t even slow it down.”

The reality of their situation was a crushing weight. But despair was a luxury they couldn’t afford. The System refreshed its tasks daily. If they wanted to survive, they had to grind. There was no other way.

Later, in the privacy of his quarters, Jax sat down to open the letter Silas had brought back. Barnaby sat on the edge of the bed, watching with wide, expectant eyes.

Barnaby couldn’t read, but he knew the handwriting belonged to his sister.

Jax scanned the signature and let out a genuine, weary laugh.

“Big Dummy,” Jax read aloud, shaking his head. “She really stuck with that nickname? I’m the handsome savior of the wasteland, and she calls me ‘Big Dummy’?”

He looked at Barnaby, who was grinning ear to ear.

“Alright, listen up,” Jax said, summarizing the contents. “She says don’t worry about her. She says if we make money, we shouldn’t blow it on stupid things. And most importantly, she says if you lose a single hair on your head, she’ll come back and kill me herself.”

Barnaby giggled, clapping his large hands.

But as Jax read further, his expression sobered. The letter mentioned The Elysium Lounge.

Memories surfaced, unbidden and sharp. Years ago, Jax had been a low-ranking member of the city defense team. When he took a shrapnel wound that nearly cost him his leg, he had no credits for surgery. He was useless, crippled, and dying.

It was Elena—Barnaby’s sister—who had stepped up. She was just a girl then, but she shouldered the burden of three lives. She signed a contract with The Elysium Lounge, selling her freedom to pay for his operation.

She saved him. He owed her his life.

“We’re getting her out,” Jax said, folding the letter and tucking it into his vest. “I’m going to Redrock Bastion, and I’m not coming back without her.”

With the base upgrades complete, the fortress could run itself for a few days. As long as he wasn’t physically present to trigger the System’s dynamic difficulty scaling, the attacks would likely revert to standard wasteland encounters—Sandworms and stray Creepers. Silas and the team could handle that.

That evening, Jax pulled Annie aside.

In the chaotic hierarchy of the wasteland, seventeen-year-old Annie was the moral compass of the group. She was sharp, kind, and fiercely loyal.

“Annie, you’re in charge of the power grid,” Jax said, handing her a heavy pouch containing fifty Energy Shards. “Here are the reload protocols for the Sentry Towers and the Howitzer. Keep them fed. Don’t hesitate to fire if you see movement.”

“I won’t let you down, Jax,” she said, clutching the pouch to her chest.

The farewells were harder than expected. Barnaby was a wreck, sobbing uncontrollably as he hugged Jax, his massive frame shaking with grief.

“I’ll be back, Barney,” Jax said, patting the giant’s back. “And I’m bringing Elena.”

“Promise?” Barnaby blubbered, wiping his nose on his sleeve.

“Promise.”

Gareth stepped forward, offering a firm handshake. “Boss Jax. Don’t worry about the rear. We’ll guard our home. No monster is getting through these gates.”

Home.

The word struck a chord in Jax. He nodded, seeing the resolve in their eyes.

“Good. Guard our home. I’ll see you soon.”

Jax walked into the darkness, the drizzle tapping a steady rhythm against his new poncho.

The road to Outpost 15 was a slurry of mud and oil. His boots squelched with every step, and the desire for a vehicle—an ATV, a jeep, anything with an engine—gnawed at him. Walking was for targets.

When he reached the entrance of Outpost 15, the first thing he checked was the bounty board.

His poster was there, but it was waterlogged and peeling. The text was illegible, and a new notice had been pasted halfway over it.

“Finally,” Jax exhaled, the tension in his shoulders releasing. “I’ve shed the identity of a wanted criminal. I can walk in the front door.”

He pulled his hood down slightly and entered the bustling district.

Despite his low profile, heads turned. Whispers rippled through the crowd like a contagion.

“Hey, look. Is that him?”

“That’s Jax. The guy from the valley.”

“I heard he killed five thousand Sandworms single-handedly. Just… pulverized them.”

“Five thousand? You’re an idiot. My cousin said it was ten thousand. And he choked out a Tier 3 Arachnid with his bare hands.”

“Damn… he must be loaded. Think of the Cores he’s holding. He could probably buy a mansion in The Sprawl with chump change.”

“He’s the one feeding the slums, right? The meat shipment?”

“Yeah. A living legend. Cold as ice and twice as deadly.”

Jax kept walking, his face twitching with a mixture of annoyance and amusement.

Ten thousand bare-handed?

The rumor mill was spinning out of control. At this rate, by the time he reached The Sprawl, they’d be saying he breathed fire and ate tanks for breakfast.

“Great,” Jax muttered to himself, stepping over a puddle. “Now I have to live up to being a mythical demigod. Just what I needed.”
